Raj-Ranpur is a small town in the district of Nayagarh in the eastern Indian state of Odisha. The town is also known as Ranpurgarh or simply Ranpur as per the modern usage. The town is historically significant especially during the British Raj when it was the capital of the princely state of Ranpur. The martyrs Shaheed Raghu-Dibakar(Raghunath Mohanty and Dibakar Parida) who were hanged for their resistance to British rule belong to this place.
Location and geography 
The town is situated at the foothills of Maninag Hills which is a hill-system covering the whole of Ranpur and much of the surrounding areas. It is one of the most important towns in the Nayagarh district and also one of the important places in Odisha. It is situated at a distance of 63 kilometres south-west of the state capital Bhubaneswar. The area covering the town and the surrounding areas experiences a tropical climate as is experienced in most parts of the state. There are numerous fountains and water streams originating and running through the Maninag Hills. Mandakini (also known as Malaguni) is the traditional river associated with the place. Presently this river is in a very bad condition and has almost dried up. It is said that one of the poets of Odisha, Kabibara Radhanath Ray(Poet Radhanath Ray) composed many of his poems sitting beside the Malaguni river while enjoying its beauty.
The area is home to one of the biggest biodiversities in the state of Odisha. The varied vegetation includes Coconut trees, Mango trees, teakwood among others. There is also a protected rubber plantation in the area. Apart from these, the place is also important in the agriculture map. Crops like paddy, sugarcane, moong (green gram) are grown in the area making the people of Ranpur self-sufficient in terms of foodgrains available to the people. The crops in this area have faced drought many times because of many factors including the changing climate and the absence of a proper farm irrigation system in the area. This place is famous for its cashew plantation. The king's palace is one of the oldest palaces of Odisha.
The area which is now part of the Ranpur town and the surrounding villages have continuously been inhabited by humans since the ancient times. The Maninag Hills has many rocks and geological features which indicate the continuous inhabitation of the area by humans and other animals. As per the traditional legend associated with the place, there used to be an Asura (Demon) named Ranasura who was creating trouble for the population and making their life miserable. The king of Ranpur was able to defeat the demon and kill him. The place has taken its name from the demon and was known as Ranasurapura during the ancient times. The name had changed to Ranpur with due course of time.
Irrespective of the assertion that the place has seen continuous human inhabitaion since ancient times, for many scholars and historians, the place was a vast wilderness almost till early medieval times. During the later medieval times, the Kingdom of Ranpur was established. The rulers of Ranpur were in continuous battle with the rulers of surrounding small kingdoms. Many times battles were fought between the rulers of Nayagarh and Ranpur with several military reverses inflicted on each other.
Since late medieval times, the rulers of Ranpur have shown their allegiance to the prominent rulers of Odisha. Ranpur has remained as a vassal kingdom of the Surya dynasty of Odisha which had famous kings like Kapilendra Deva, Purushottama Deva and Prataparudra Deva. After 1568, when Odisha fell to the Afghans of Bengal, the rulers showed their allegiance to the Afghans. Shortly afterwards in 1592, Odisha became part of the Mughal Empire after the successful military campaign of Man Singh against the Afghans of Bengal. The rulers of Ranpur again showed allegiance to the Mughals.
In 1803, the British occupied Odisha and started administering it as a part of Bengal Presidency. Modern Odisha became a Division within the Bengal Presidency. The rulers of Ranpur along with rulers of other small states and estates within Odisha showed their allegiance to the British. Ranpur formed part of an administrative unit under the British known as the Odisha Tributary States which consisted many princely states of Odisha. Initially the Odisha Tributary States was attached administratively to the Bengal Presidency. On 1 April 1912, Odisha was separated from Bengal and formed part of a new province called Bihar and Odisha. Accordingly the Odisha Tributary States came to be attached with the Province of Bihar and Odisha and its administration came under the Governor of Bihar and Odisha. The Odisha Tributary States was also known as the Odisha States Agency. On 1 April 1936, Odisha and Bihar became separate provinces and the Odisha States Agency now became associated with the newly formed Odisha province which consisted of six districts: Balasore, Cuttack, Puri, Ganjam, Koraput, Sambalpur. Meanwhile on 1 April 1933, the Odisha States Agency was merged with the Eastern States Agency which directly came under the administration of the Governor-General instead of a provincial Governor. After India achieved its independence, Ranpur along with the other 23 princely states within the Odisha States were merged with the Province of Odisha. After the independence and merger, many small and medium sized princely states were made part of surrounding districts or part of newly formed districts. As such Ranpur became part of the Puri district in 1949.
By the end of 1950, Odisha had 13 districts. Between 1949 and 1993, Ranpur formed part of the Nayagarh Sub-Division within Puri district. In 1993, during the Janata Dal government of Odisha, the Chief Minister of the state Biju Patnaik resolved to increase the number of districts from 13 to 30. As per this resolution, the erstwhile Puri district was trifurcated into three districts, namely Nayagarh, Puri and Khordha in 1993. With this division and creation of new districts, Ranpur became part of the Nayagarh district on 1 April 1993 and this status continues till today.
